Information for Writing PDF417 and MicroPDF417 Barcodes with LEADTOOLS SDK

PDF417

PDF417 is a multi-row barcode symbology with high storage capacity and
error-correction capabilities. It can be read by linear barcode readers, laser
scanners, and 2d barcode scanners. PDF417 barcodes can store 1,108 bytes, 1,850 text characters, or 2,710 digits.
A barcode is made up of 3 to 90 rows stacked into columns.

Each row consists of:

Leading quiet zone (the required minimum amount of white space before the barcode begins)

Start pattern

"Row left" codeword

1 to 30 data codewords

"Row right" codeword

Stop pattern

Trailing quiet zone

Depending on the encoding scheme, a codeword can contain:

1.2 bytes when using Binary Encoding

2 characters when using Text Encoding

2.9 digits when using Numeric Encoding

MicroPDF417

MicroPDF47 is derived closely from the PDF417 specifications. It is designed
for applications that require improved area efficiency without the maximum data capacity of PDF417. As a result it has
a limited number symbol sizes with fixed Error Correction for each symbol size.
